Naba Banerjee is the person in charge of Airbnb’s worldwide ban on parties. She has spent three years developing strategies to combat partying and design an anti-party AI system. The company defines a party as a gathering that disrupts neighbors and the community, and Banerjee’s system has helped reduce party reports by 55% and block or redirect over 320,000 guests from booking attempts. Airbnb’s business is growing despite the post-pandemic travel boom fading. Banerjee, a mother of five, used her personal experience to develop algorithms and safeguards. She worked with her team to create a neighbor-checking AI system to prevent parties.
